When asking for a can of soda, or a drink while ordering food, do you ask for a “soda,” a “pop” or a “coke” (regardless of brand or flavor)? Your choice of terminology most certainly has roots on where you, or your family, has, well… roots from!

The word you use generally boils down to where you’re from: Midwesterners enjoy a good pop, while soda is tops in the North and far West. Southerners, long the cultural mavericks, don’t bat an eyelash asking for coke – lowercase – before homing in on exactly the type they want: Perhaps a root beer or a Coke, uppercase.

So how did “soda” come to be called so many different things in different places?

It all stems from a mix of economic enterprise and linguistic ingenuity.

The popularity of “soda” in the Northeast likely reflects the soda fountain’s longer history in the region. Since a lot of Americans living in the Northeast migrated to California in the mid-to-late 1800s, the name likely traveled west with them.

As for the Midwestern preference for “pop” – well, the earliest American use of the term to refer to a sparkling beverage appeared in the 1840s in the name of a flavored version called “ginger pop.” Such ginger-flavored pop, though, was around in Britain by 1816, since a Newcastle songbook is where you can first see it used in text. The “pop” seems to be onomatopoeic for the noise made when the cork was released from the bottle before drinking.

Linguists don’t fully know why “pop” became so popular in the Midwest. But one theory links it to a Michigan bottling company, Feigenson Brothers Bottling Works – today known as Faygo Beverages – that used “pop” in the name of the sodas they marketed and sold. Another theory suggests that because bottles were more common in the region, soda drinkers were more likely to hear the “pop” sound than in the Northeast, where soda fountains reigned.

As for using coke generically, the first Coca-Cola was served in 1886 by Dr. John Pemberton, a pharmacist at Jacobs’ Pharmacy in Atlanta and the founder of the company. In the 1900s, the Coca-Cola company tried to stamp out the use of “Coke” for “Coca-Cola.” But that ship had already sailed. Since Coca-Cola originated and was overwhelmingly popular in the South, its generic use grew out of the fact that people almost always asked for “Coke.”

As with Jell-O, Kleenex, and Band-Aids, it became a generic term.

And speaking of soft drinks, what’s up with that term?

It was originally used to distinguish all nonalcoholic drinks from “hard drinks,” or beverages containing spirits.

Due to the growing popularity of soda water concoctions, eventually “soft drink” came to mean only such sweetened carbonated beverages, a linguistic testament to America’s enduring love affair with sugar and bubbles.

With the average American guzzling almost 40 gallons per year, you can call it whatever you what. Just deliver it cold, please!
